Alcohol does evaporate when heated, but it is a myth that it completely cooks out of a dish. The rate of evaporation depends on various factors, including temperature, surface area, cooking time, and the dish's other ingredients. While heating alcohol for longer periods reduces its alcohol content, it never entirely disappears. According to studies, simmering a dish with alcohol for 15 minutes retains 40% of the alcohol, 35% after 30 minutes, and 5% after 2.5 hours. The type of alcohol used also matters, as different alcohols have varying alcohol by volume (ABV) percentages. For individuals who avoid alcohol for health, ethical, or religious reasons, cooking with alcohol may pose a concern, and alternative ingredients can be used to replicate flavors.

What You'll Learn
Alcohol begins to evaporate at 173°F
Alcohol has a lower boiling point than water, which means it evaporates more quickly. The boiling point of ethanol, the type of alcohol found in beverages, is approximately 173°F (78.4°C), while water boils at 212°F (100°C). This means that alcohol begins to evaporate at a lower temperature, and cooking with alcohol will see an increase in vapour as the dish heats up.
The amount of alcohol that evaporates depends on several factors, including the cooking method, temperature, duration of cooking, and the surface area exposed to the air. The higher the temperature, the quicker the evaporation, and the longer the cooking time, the greater the cumulative evaporation. For example, simmering a dish for about 30 minutes can significantly reduce alcohol content, while boiling it for more than an hour can reduce it even further. According to the USDA, it takes 15 minutes of constant simmering to eliminate 60% of the alcohol in a dish, and up to 2.5 hours to get rid of 95%. However, it's important to note that alcohol never entirely cooks off, and a small proportion of alcohol molecules will remain bonded to water molecules in the mixture.
The type of dish being cooked also makes a difference. Beer cheese sauce, bourbon caramel, and other sauces that are brought to a boil and then removed from the heat typically retain about 85% of the alcohol. Marinades that are not cooked can maintain up to 70% of the added alcohol, while meats and baked goods that are cooked for 25 minutes without being stirred retain 45%. Stews that simmer for 2.5 hours tend to have the lowest amounts, retaining about 5%.
While cooking with alcohol can enhance the taste profile of a dish, it's important to be aware that not all of the alcohol will evaporate, and it may not be suitable for children, pregnant women, or those in recovery from alcohol use disorders.

It takes 2.5 hours to eliminate 95% of alcohol
It is a common misconception that alcohol "cooks out" of dishes that are brought to a simmer. Alcohol begins to evaporate as soon as it is heated to 173°F (78.3°C). However, it takes much longer for most of the alcohol to evaporate. According to studies by the USDA, it takes 15 minutes of constant simmering to eliminate 60% of the alcohol in a dish and up to 2.5 hours to eliminate 95% of it. The dish will still retain about 5% of its alcohol content after 2.5 hours of baking or simmering.
The rate of evaporation depends on several factors, including the dish's other ingredients, the cooking temperature, and the cooking time. The higher the temperature, the faster the alcohol will evaporate. For example, sauces brought to a boil and then removed from the heat retain about 85% of the alcohol, while meats and baked goods cooked for 25 minutes without being stirred retain about 45%. The size of the pan also matters—a larger pan provides a greater surface area for the alcohol to evaporate from.
While it is challenging to eliminate all traces of alcohol from a dish, it is important to note that the amount of alcohol typically used in recipes is small enough that it is highly unlikely to cause intoxication, even if the dish is served uncooked. However, it is recommended to consider alternative ingredients when preparing food for children, pregnant women, or those in recovery from alcohol use disorders.
In summary, while it is not possible to completely eliminate alcohol from a dish through cooking, the majority of it can be removed through prolonged heating. The specific amount of time required depends on various factors, including temperature, cooking time, and the size of the pan.

Alcohol never entirely cooks off
The amount of alcohol that remains depends on several factors, including the recipe's other ingredients, the temperature it is cooked at, and the length of time for which it is cooked. For example, the size of the pan matters: more alcohol remains in recipes made in smaller pans because a larger pot has more surface area, allowing more alcohol to evaporate. Additionally, recipes that require stirring during the cooking process tend to have lower amounts of alcohol because stirring promotes evaporation.
According to the U.S. Department of Agriculture (USDA), baked or simmered dishes that contain alcohol will retain 40% of the original amount after 15 minutes of cooking, 35% after 30 minutes, and 25% after an hour. However, there is no point at which all of the alcohol disappears. Baking or simmering an alcohol-containing dish for 2.5 hours will still leave 5% of the alcohol content behind.
While it is highly unlikely that dishes cooked with alcohol will cause intoxication, it is important to note that the alcohol does not completely disappear. Therefore, individuals in recovery, pregnant or breastfeeding women, and those who choose not to drink for religious, health, or other reasons may need to opt for alternative ingredients or recipes that do not include alcohol.

Higher temperatures and larger surface areas increase evaporation
Alcohol begins to evaporate as soon as it is heated to 173°F (78.3°C). The rate of evaporation increases with temperature because as the temperature increases, the amount of energy required for evaporation decreases. Warmer air can hold more water vapour, so evaporation rates are higher in warmer temperatures.
The size of the pan in which the alcohol is cooked also affects the rate of evaporation. The greater the surface area, the more alcohol molecules are exposed to the air, and the faster they will escape. Therefore, a larger pie will have less alcohol than a smaller pie of the same recipe.
According to the USDA, it takes 15 minutes of constant simmering to eliminate 60% of the alcohol in a dish, and up to 2.5 hours to eliminate 95%. However, some sources claim that alcohol never entirely cooks off, and that a small proportion of alcohol molecules will always remain bonded to water molecules.

Alcohol can be absorbed into solid components of food
Alcohol does not "cook out" completely, even after extensive heating. A small proportion of its molecules will remain bonded to other molecules, such as water, that are present in the mixture. The amount of alcohol that remains varies depending on several factors, including the recipe's other ingredients, the temperature it is cooked at, and the length of time for which it is cooked. The higher the temperature and the longer the cooking time, the greater the evaporation.
According to the USDA, alcohol begins to evaporate when heated to 173°F (78.3°C). It takes 15 minutes of constant simmering to eliminate just 60% of the alcohol, and up to 2.5 hours to get rid of 95%. These times can vary depending on the specific food the alcohol has been added to, as well as the size of the pan it's cooking in. For example, there will be less alcohol in a beurre blanc sauce simmered in a large stockpot than in a small saucepan.
Beer cheese sauce, bourbon caramel, and other sauces brought to a boil and then removed from the heat typically retain about 85% of the alcohol. Cherries jubilee and other recipes that flame the alcohol may still have 75% of the alcohol. Marinades that are not cooked can maintain as much as 70% of the added alcohol. Meats and baked goods that are cooked for 25 minutes without being stirred retain 45% of the alcohol. Stews and other dishes that simmer for 2.5 hours tend to have the lowest amounts, retaining about 5% of the alcohol content.
It is important to note that the amount of alcohol in a dish after cooking depends on the original alcohol content of the liquor used. For example, when cooked under the same conditions, beer (with an ABV of 3.5-9%) and rum (with an ABV of 40-75.5%) will evaporate at the same rate. However, because of its higher starting ABV, rum will have a higher alcohol content after cooking.
While it is highly unlikely that dishes cooked with alcohol will cause intoxication, an alternative might be preferable when preparing food for children, pregnant women, or those in recovery. There are simple substitutions that can replicate similar flavors, such as using coriander and malt syrup to mimic the taste of beer or vinegar to replace wine.

Frequently asked questions
Alcohol does evaporate when heated, but it doesn't disappear completely. The longer you cook, the more alcohol cooks out. According to studies, it takes 15 minutes of constant simmering to eliminate 60% of the alcohol, and up to 2.5 hours to get rid of 95%.
Yes, the type of alcohol does make a difference. For example, beer typically has an ABV of 3.5-9%, while rum is around 40-75.5%. So, even when cooked for the same amount of time, the completed dish with rum will have a higher alcohol content than the one with beer.
Yes, the cooking method can impact the amount of alcohol that remains. For instance, flambé, which involves heating alcohol to the boiling point, will still retain 70-75% of its alcohol content. On the other hand, dishes that simmer for 2.5 hours tend to have the lowest amounts, retaining about 5% of alcohol.
Yes, the size of the pan matters. The greater the surface area, the more the alcohol molecules are exposed to the air, and the faster they will evaporate. So, a dish cooked in a larger pan will have less alcohol than the same dish cooked in a smaller pan.
While the amount of alcohol in recipes is typically small, it is important to consider who will be consuming the dish. For children, pregnant women, those in recovery, or individuals who abstain from alcohol for religious or health reasons, it may be preferable to use non-alcoholic alternatives or avoid dishes cooked with alcohol altogether.
